ATTORNEY United States Patent 2,992,610 PRINTERS CHASE Marvin H. Hammer, 1724 W. Mulberry, Phoenix, Ariz. Filed Jan. 7, 1960, Ser. No. 1,113 2 Claims. (Cl. 101-404) This invention pertains to improvements in a printers chase and is particularly directed to a chase frame structure for automatically securing groups of imposed type for easy and safe handling and for quick assembly and disassembly of the type.

One of the objects of this invention is to provide a printers chase frame comprising a plurality of pieces which are locked together about the imposed type by the normal spring action interlock of the parts.

Another object of this invention is to provide an improved printers chase frame structure which completely eliminates the use of the usual tying string.

Still another object of this invention is to provide an improved printers chase comprising a plurality of steel side elements, some of which have spring urged forces for holding the imposed type during handling and setting up while at the same time providing a locking arrangement for the chase and imposed type when presented in the printing press.

Further features and advantages of this invention will appear from a detailed description of the drawings in which:

FIG. 1 is a perspective exploded view showing the printers chase incorporating the features of this invention.

FIG. 2 is a plan view showing the printers chase of FIG. 1 in use holding the imposed type.

FIG. 3 is a similar plan view but showing the chase clamped in the press structure.

As an example of one embodiment of this invention there is shown a printers chase comprising the side members and 11 each having turned in hooked ends 12 and the end members 13 and 14 each of which has cutwardly laterally extending ends 15. The end members 13 and 14 are of resilient material and are bowed outwardly at 16 in the direction of the laterally extending ends 15. Preferably the width of the pieces 10, 11, 13 and 14 is substantially equal to the base height of the imposed type 17.

In assembling the chase, the typesetter hooks together the side members 10 and 11 with the end member 14 as shown in FIG. 2. and places them on the usual plate or pallet and then assembles the imposed type 17 therein. After the chase is loaded the final member 13 is slid down laterally in hooked together position whereupon the side members 10 and 11 are held against the sides 18 and 19 of the imposed type 17 while the bowed end members 13 and 14 contact the imposed type 17 at the points 20 so as to provide a preloaded pressure on the sides and ends of the imposed type. In this condition the type slugs and spaces of the imposed type 17' are thus held securely intact so that the loaded chase can be safely 2,992,610 Patented July 18, 1961 handled from the plate to a pallet and then to the press platen.

In FIG. 3 the loaded chase is shown mounted in the printing press, the sides 10 and 11 being locked against the side clamps 21 and 22 of the press. The end members 13 and 14 are clamped between the end clamps 23 and 24 of the press, these clamps flattening out the bowed end members 13 and 14 when clamped up in the press so as to securely lock the type in the chase in the press. Release of the press clamps allows the end members to bow out again holding the imposed type safely in the chase for further handling.

While the apparatus herein disclosed and described constitutes a preferred form of the invention, it is also to be understood that the apparatus is capable of mechanical alteration without departing from the spirit of the invention and that such mechanical arrangement and commercial adaptation as fall within the scope of the appendent claims are intended to be included herein.

Having thus fully set forth and described this invention What is claimed and desired to be obtained by United States Letters Patent is:

1. A printers chase comprising, a first straight side member having turned in hooked ends, a second straight side member having turned in hooked ends, a first end member having outwardly laterally extending ends, a second end member having outwardly laterally extending ends, each of said end members being constructed of resilient material and bowed outwardly intermediate their ends in the direction of said laterally extending ends, all of said side and end members being of equal width substantially equal to the base height of the imposed type in the chase, said end members when initially assembled with said side members having their inner faces contacting said imposed type at the ends of said end members directly opposite said outwardly laterally extending ends so that when side pressure is exerted on the bowed portion of said end members intermediate their ends the outer edges of said outwardly laterally extending ends move outwardly longitudinally of said side members to securely lock all of said members to the imposed type.

2. A printers chase as set forth in claim 1 wherein said inner face points of contact of the end members function as a fulcrum heel area against the imposed type causing the outer edges of said outwardly laterally extending ends to move laterally outwardly into said hooked ends when said end members are deformed from bowed outward position to straight condition against the imposed type.
